                <dependency>
                    <groupId>mysql</groupId>
                    <artifactId>mysql-connector-java</artifactId>
                    <version>8.0.21</version>
                    <!-- 注意mysql版本与你使用的一致 -->
                </dependency>
                <dependency>
                    <groupId>tk.mybatis</groupId>
                    <artifactId>mapper</artifactId>
                    <version>4.1.5</version>
                </dependency>

这两个是插件依赖，你的IDEA没有自动下载依赖，所以导致红色报警。你可以先把这两段移到

<dependency>
        <groupId>org.projectlombok</groupId>
        <artifactId>lombok</artifactId>
        <version>1.18.16</version>
        <scope>provided</scope>
    </dependency>

后面，让IDEA就会自动下载依赖，下载完成后，再贴回这里即可。

  老师我用的oracle能用这个专用mapper么，也是出现4.1.5无法下载，如果是依赖mysql-connector-java我没用mysql该怎么搞，我看了github半天没找到有oracle该怎么配置

  调了半天调通了
